It is a permission issue. Are you sure that the account "hadoop" has read
and write access to /usr/local/* directories?

The installation of Hadoop has always been effortless for me. Just follow
the instructions step by step given on:
http://hadoop.apache.org/common/docs/stable/single_node_setup.html
